NIC does not connect after installation


I recently moved my installation from a HP Compaq to a dell Poweredge 850 and then my problems started. The installation was performing as my squid for my network; and was running openSuse 12.4. First of all the screen’s resolution was too low i believe its 640 by 600 and i have searched for a gui console too do the adjustment. then i now discovered that one of the network cards that was connected to the modem was reading that it was not connected even though it was.

I now took the lazy man’s way out and did an upgrade to OpenSuSE 13.1 and exactly the same thing is still happening! the 1st NIC is refusing to connect when plugged and then the 2nd NIC is ok! and also the screen’s resolution was too low i believe its 640 by 600!

I have searched for any similar problems of this sort and could not find any. Although i found out from a mere glance at goole querying that it seems that HP seems to be more compatitible with OpenSuSE than Dell as i can see more problems with Dells than with any HP systems and also i can see on many review pages that they have actually tested the HP pcs with OpenSuSE than with Dells! Please i stand to be corrected.

Can you please explain how you “upgraded”. That is a very generic word that can point to several different pathes obe can follow.

And explaining how your NIC are configured wouldn’t be bad also. Traditional using “ifup”, using NetworkManager?

Is your NIC (in fact both NICs) detrected when using YaST?

(BTW it is openSUSE, not the different mix of uper and lower case characters you use ;))


Thanks for your response.
I did a fresh installation from 12.4 to 13.1. And i used the Network the Traditional method Using the “ifup” for the 2 NICs.
And yes the 2 NICs were detected when using the YAST.
I apologise for my error in the way i spelt openSUSE, it wont happen again.

Thanks once again.

BTW this is about your network problem. For the screen resolution, please open a new thread in the relevant (sub)forum). Mixing of unrelated questions/problems is not efficient.

It is still a bit strange what you tell, because 12.3 is the highest released 12.n version. 12.4 does not exist???

Having two NICs, what are you using them for?

How did you configure them? Maybe that qusetion is best anwered by

ls /etc/sysconfig/network/ifcfg-*

to see how they are called. And then for each of them:

cat /etc/sysconfig/network/ifcg-<what you found>

I see, you are new here, thus it may be useful to point you to the way to post such computer output here in a post. You copy/paste the prompt, the command, the output and the next prompt in one sweep between CODE tags in the post. You get those CODE tags by clicking on the # button in tthe tool bar of the post editor.


i said in my first posting that i am using this as my squid!

Also i got my digits (12.4 instead of 12.3) wrong the same way i got my spelling for the openSUSE wrong ad i apologise!

I used the YAST and and chose to use the Traditional method “ifup”, i did not do it via CLI in fact i am a bit wary of CLI as i hear that when one makes mistakes in the CLI to repair it might prove difficult. So due to that i always try to use the GUI to do almost everything, and to be more truthful its easier also.

In the YAST Network Panel i saw the 2 NICs but only one of the 2 cards was connected. I tried inputting the IP addresses and assigning routes and everything as i used to do in the 12.x (i think it is safer for me to call it that) and still it does not connect whereas the 2nd NIC without being configured with IP details and all shows that it is connected!

Yes i am very new here, in fact less than a day old!
